Written by Jakub Rusinowski · Last updated February 15, 2026
Yes
Yes — MiniMax M2.5 230B at Q2_K needs about 79.9 GB of the 96 GB usable on MacBook Pro 16" (M5 Max, 128 GB) (~16.1 GB spare), at ~56.2 tok/s (estimated), with room for about 32,768 tokens of context.
Confidence: medium · Recommended quantization: Q2_K · Estimated speed: ~56.2 tok/s

What to watch out for
- Q2_K is the only quantization that fits, and it is a heavily degraded one — expect noticeably worse output than the same model at Q4_K_M. A smaller model at Q4 is usually the better trade.
- 1 larger variant of MiniMax M2.5 does not fit and would need CPU offload or different hardware.
- This model does not publish its full attention configuration, so the KV-cache share of these figures is inferred from its parameter count rather than computed exactly.
- Memory on this machine is not upgradeable, so the configuration you buy is the ceiling for every model you will ever run on it.
MacBook Pro M5 Max 128 GB limitations
- Unified memory is soldered and cannot be upgraded after purchase.
Recommended setup
Ollama or LM Studio (Metal) — MLX for the fastest Apple-native throughput
How these numbers are calculated
- Memory need = quantized weights + KV cache at 8,192 tokens (f16) + 0.8 GB runtime overhead.
- 128 GB unified memory at 614 GB/s, shared between CPU and GPU.
- macOS reserves a share of unified memory for the system, so not all of it is available to a model.
- Throughput is a memory-bandwidth roofline estimate, not a measurement. It is labelled "estimated" everywhere it appears.
- KV cache is inferred from the parameter count because this model does not publish its full attention configuration.
